Colors adjustment in Compro M1F

[Fire Foxer]

hi
i have question about adjustmenting the colors in the tv card
because the default colors of the card are not exact and the result seems to be
nucleated and times - brighten the times darken
i've upped a bit contrast and downed some brightness
and still its not exact
is there anyway to know the exact colors of the card or is it only matter of playing with it?
this is how it looks now:

You have to test until it looks good. I doubt you will find any "exact" color settings.
